characteristic

The color of Ginkgo Garden is light green, which is different from the leaves of Fraxinus mandshurica. It consists of leaves and petioles, and there is a big wave at the top of the leaves. The whole looks like a fan. Ginkgo orchards sprout every spring. In summer, leaves grow into small fans. In autumn, leaves, like gray leaves, gradually turn golden yellow. At the end of autumn, the breeze blows, and they chase and play like lovely butterflies. This scene is really intoxicating. In winter, leaves that fall to the ground will be submerged by dust.

2. Maple Leaf

characteristic

Maple leaves are palmately 5-lobed, about 13 cm long, and slightly wider than long. The three largest lobes have several prominent teeth, the base is heart-shaped, the upper part is medium green to dark green, and the lower part is hairy, which turns from yellow to orange or red in autumn.

Deciduous tree species will have some chemical reactions in autumn and winter, so that the substances or some tissues contained in the original leaves can be recycled and stored in stems or roots, which can be reused next spring. Chloroplast and chlorophyll are one of the objects to be decomposed and recycled, because the chlorophyll content is high, which covers other colors and makes the leaves green. So when the chlorophyll in the leaves is gone, the colors of other pigments are highlighted, such as the red of anthocyanin, the yellow of carotene and the yellow of lutein. In addition, the sugar stored in maple leaves will be decomposed into anthocyanins, making the leaves more colorful and fiery red.

3. Bamboo leaves

characteristic

Bamboo leaves are narrowly lanceolate, 7.5 ~ 16 cm long and 1 ~ 2 cm wide. The apex is acuminate, the base is blunt, the petiole is about 5 mm long, one side of the edge is smooth, and the other side is serrate and rough. Parallel veins, 6 ~ 8 pairs of secondary veins, small transverse veins are very significant; The leaves are dark green, hairless, the back is lighter, and the base is slightly hairy; Thin and brittle. Light breath, light taste. It is best to be green, complete and unbranched.

characteristic

The leaves are 8- 16 cm long and 9- 18 cm wide, and 5-7 deeply split to the middle or lower part, with narrow and long lobes. When I was young, I was covered with gray-yellow stellate villi and then fell off.

The leaves are oblong, 2-3 meters long and 25-30 cm wide, with obtuse top, round or asymmetrical base, bright green and shiny.

characteristic

When the seedlings are unearthed and the cotyledons are unfolded, the primary leaves appear first, which are solitary, spirally arranged, linear and lanceolate, and the leaf margin is toothed. It takes 1 ~ 3 years for primary leaves to function as leaves, and then there are needles, usually 2, 3 or 5 bundles, which are inserted at the top of short branches. Each bundle of needles has a leaf sheath at the base, which falls off or exists early. The position of resin channel in mesophyll tissue is relatively constant in adult plants, which can be divided into three types: exogenous, mesophyll and endogenous. There are 1 or 2 vascular bundles in the cross section of pine needles, and the vascular bundles can be combined in the double vascular bundle pine under special circumstances.
